Cybersecurity, what is data protection and what it is today

La advanced connectivity and data exchange is the key to the future and, to a large extent, already now, transport and logistics: from fleet managementbig and small, to monitor traffic, everything travels around the network. A network that needs to be protected and protected due to its growing importance. Make data available and at the same time Protect them from hacking and rework is actually a particularly challenging task.

A concept that will become more and more important as data traffic will apply to public safety and autonomous driving, which is based precisely on open communication and which will have a turning point with the spread protocol 5G communications that are in the process of spreading, but which will also require a high level of global availability and therefore must provide adequate guarantees to protectdata integrity transferred.

Most frequent attacks

Trying to breaking networks are mainly of two types: passive, which do not change data, but aim at improperly obtaining confidential information, and actual intervention: the first type includes actions determined by Breathing in и Portal scan.

Specifically, Sniffing (which can be translated as "sniffing") consists ofdata interception in a path on the network that can be stored and used to obtain information about traffic itself, while a portal scan (port scan) aims to analyze servers or hosts and identify active ports and connected users... These are actions that are also performed in a perfectly legal way in order to check and monitor your network.

Attacks of the second type are attacks aimed at damage, blocking or disabling a particular program or an entire network for malicious purposes or for the purpose of blackmail. The danger that, above all, institutions, subjects and large companies they are well aware and from which they must be protected by special data protection systems.

Countermeasures

Data protection is based on cryptography, that is, a coding system that makes data readable only by authorized users through network protocols. However, it can help protect his privacy in private system, while for shared networks based on the principle of accessibility, the data must be accessible, but at the same time protected from unauthorized access.

Blockchain Possible Solution

Among the technologies indicated as possible means of countering the risks of attacks is blockchain technology, that is, a data structure organized according to the concatenation of blocks. Its special "diffuse" structure and decentralized, and the property of being accessible, but not mutable, makes it especially difficult to attack and interrupt.
